Build scmgit-base without pthreads

[Stephen Nelson-Smith <sanelson%gmail.com@localhost>]

Hello,

I'm seeing exactly the issue described in this thread on the Git
mailing list.:
http://git.661346.n2.nabble.com/Unable-to-fork-off-sideband-demultiplexer-td6427108.html

My system is Solaris 9, with pkgsrc-bootstrapped gcc3.4.

Upon a git clone I see:

error: cannot create thread: Unknown error
fatal: fetch-pack: unable to fork off sideband demultiplexer
Segmentation Fault (core dumped)

The fix/workaround seems to be to build Git without pthreads.  I
appended NO_PTHREADS=YesPlease to MAKE_FLAGS in scmgit-base Makefile,
and rebuilt it, and it worked.

Questions:

1) Is  this the best approach?  Should there be a Makefile patch?  It
feels kinda dirty to have to hack the Makefile
2) What's the best way to share this for other users, so they don't get bitten?

S.
